Well, for the people saying that Season 1 isn't over yet, a season is, well a season. Around 13 weeks so thats 13 episodes which is a typical season in anime. Of course, filler anime are different, I'm sure a season in filler anime is each arc. So in this case Season 2 would be from now (episode 12 or 13?) to around 24 to 26.

This image shows partly why anime can look better than real life, the stylized Nanami figure is one I don't think could exist in real life, like a Barbie(tm) doll. Overall in anime you can make things that are just... sigh... perfect. No, more perfect than perfect. More perfect than is possible.

I hope Sorata and Mashiro get together so I can console Nanami LOL. If only I were back in high school again, eh? That's why I love these shows, the high school first love scenario... reminiscing about those times is fun. Would have been really fun if it had happened like this... but for some reason no one wore maid outfits or thigh highs at my school... wrong school I guess ;)

Yeah, I understand what you're saying, and honestly I don't think you're wrong. But please allow me to tell you my opinion on how I think seasons work:
When a series is ordered, they have a set number of how much they have to make. With that set number that ordered, that's how I consider what a season is. I would just say this will be a complete series until they order more episodes. However; with anime like Naruto and its arcs, yeah I don't want to get into that because I won't know where to start with that and even then if my answer will have some sort of understanding. If that didn't make any sense to you, I'll try my best to explain just not here anymore because I'm not adding to the topic :)

My example(s) are
Medaka Box (Season one) & Medaka Box Abonormal (Season 2)
Sword Art Online (I think twenty-five episodes were ordered in the beginning and they have broken those up into two arcs. But I would just say this is a complete Series)

A lot of people still seem to get confused on this and part of the problem is confusion on the words season, series, and story arc.

A season (or cour) generally consists of 12 or 13 episodes and are broken up into the 4 seasons of the year (Fall, Winter, Spring, Summer). So when a show is 2 cours long, that's 2 seasons (approx. 24-26 eps ) versus one cour (12 or 13 eps) or 3 cours (approx 36 eps - kind of rare) or 4 cours (50 to 52 eps) etc.....

When a production committee first forms and gives the green light for production to start, they determine how many seasons (cours) the show will be. Now if that series turns out to be successful, another committee may be formed and they will make a sequel (or prequel). But this will be considered a separate SERIES. The confusion comes when local licensors/distributors market that second series as a second SEASON.....regardless of whether the first season was one, two, or even 3 or 4 cours long. But in Japan they don't do this.

Take for example "Clannad" and "Clannad After Story". Here in the West we often mistakenly refer to them as Season One and Season Two respectively. But in Japan when you see "Clannad: the Complete Series" advertised....you're only getting eps 1-24. "Clannad After Story" is considered a whole separate series. And when you see them listed in those Big Globe polls, they are listed separately as well, rather than as one SERIES. That's why they have different names. Same goes for shows like "Code Geass" and "Code Geass R2", or "K-On!" and "K-On!!" (with 2 exclamation marks). Notice they almost never use the word "season" in their marketing. That's just something we add on to it in the West.

Sometimes you might see a 2 cour series packaged as one box set in Japan and they might say "contains both parts 1 & 2". That's still 2 seasons.

A story arc is just a segment of a larger, over arching story, and does not necessarily have to line up with the start or end of a season. So something like "Sword Art Online" had several story arcs in the first season, but the second season (Alf online) wasn't a story arc, but a whole different story.

I only got through half way of the first episode. Would you reccomend me finishing the series??

Yes. The show is definitely not what it first appears to be. While it has plenty of fan service moments, there is good character development and a surprisingly good story. Watch the first 3 episodes and then make up your mind.
